AIM: To evaluate the therapeutic effects of Gamichunggantang (GCT) on hyperlipidemia through high cholesterol diet model. GCT is an Oriental herbal medication, which has been used for-the treatment of fatty liver, hyperlipidemia or alcoholic liver disease in Daejeon University Oriental Hospital, Korea since 1999. METHODS: Rats were fed with high cholesterol diet for 4 weeks and GCT was administrated for 2 weeks from 2 weeks later in expermental days. The levels of serum total cholesterol, HDL-cholesterol, and triglyceride were analyzed every week. Absolute and relative liver weight to body, and histophathological changes were determined at last day. And, lipid metabolism-related gene expressions (ACAT and DGAT) in liver tissue were analyzed by using RT-PCR. RESULTS:In GCT group, TG levels were reduced at 3 and 4 weeks after GCT administration (39.4%, P<0.05 and 36.3%,P<0.01 respectively). Total cholesterol levels also were reduced at 3 weeks (20.5%, P<0.05) and 4 weeks (35.86%, P<0.01) after GCT administration, but HDL-cholesterol levels were increased significantly (P<0.05) at 3 weeks(14.7%) and 4 weeks (25.5%) compared with hyperlipidemia-induced group without GCT. In the GCT treated group, liver weight was lower and lipid accumulation was decreased in histological finding. ACAT gene expression was suppressed compared with hyperlipidemia-induced group but not DGAT. CONCLUSION: GCT possesses preventive or therapeutic effects on diet-induced hypedipidemia by inhibiting the intestinal absorption and storage of exogenous and endogenous cholesterol.

Hot torsion tests were performed on the Al-7Mg alloy at the temperature ranging from 300 to 500℃ and strain rates between 0.05 and 5 s^(-1) to explore the progressive dynamic recrystallization(DRX)and texture *** DRX behavior of the alloy manifested two distinct stages:Stage 1 at strain of≤2 and Stage 2 at strains of≥*** Stage 1,there was a slight increase in the DRXed grain fraction(X_(DRX))with predominance of discontinuous DRX(DDRX),followed by a modest change in X_(DRX) until the transition to Stage *** 2 was marked by an accelerated rate of DRX,culminating in a substantial final X_(DRX) of~*** backscattered diffraction(EBSD)analysis on a sample in Stage 2 revealed that continuous DRX(CDRX)predominantly occurred within the(121)[001]grains,whereas the(111)[110]grains underwent a geometric DRX(GDRX)evolution without a noticeable sub-grain ***,a modified Avrami’s DRX kinetics model was utilized to predict the microstructural refinement in the Al-7Mg alloy during the DRX *** this kinetics model did not accurately capture the DDRX behavior in Stage 1,it effectively simulated the DRX rate in Stage *** texture index was employed to assess the evolution of the texture isotropy during hot-torsion test,demonstrating significant improvement(>75%)in texture randomness before the commencement of Stage *** initial texture evolution is attributed to the rotation of parent grains and the substructure evolution,rather than to an increase in X_(DRX).
